Abstract
Abstract The housing comprises a bottom 1 in the thickness of which the extension of an input/output pin 5 of the housing is embedded. This extension ends in a contact terminal 15 which lies flush with the surface of a substrate 7 carrying passive or active electronic components 11, 12 and interconnecting conductor tracks 10, 10', 10". A conductor track 10 passing over an opening 6 in the substrate which accommodates the terminal 15 is soldered onto this terminal in order to interconnect a terminal 14 of the component 12 with the input/output pin 5 of the housing. An interconnection via side terminals 13, 13', 13", . . . , which complicates the layout of the conductor tracks to be provided for this purpose, is thus no longer required.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
Housing for an electronic circuit, comprising a bottom onto which is fixed a substrate made of insulating material, at least one surface of which carries active and/or passive components and electrical conductor tracks or bands connecting the components to one another, and/or electrical contact pins emerging outside the housing so as to ensure interconnection of the circuit contained inside the housing with at least one electrical and/or electronic apparatus associated with and located outside the housing, characterized in that at least one (5) of the pins extends inside the thickness of the wall of the bottom (1) of the housing so as to pass through the surface of the bottom of the housing which supports the substrate and pass into an opening (6) formed in the substrate so as to present one end in the form of a contact terminal (15) which lies flush with the surface of the substrate carrying the conductor tracks or bands, at least one (10) of these tracks or bands passing above this opening in such a way as to be in electrical contact with this contact terminal of the pin.

Claim 3
Dependent Claim
43 words
Housing according to claim 1, characterized in that it comprises several pins, the ends of which outside the housing are aligned while the contact terminals of these pins which lie flush with the substrate surface carrying conductor tracks are dispersed over this surface.
Claim 4
Dependent Claim
82 words
Housing according to claim 1, characterized in that the substrate made of insulating material is metallized on its two surfaces in accordance with conductor track or band configurations, the contact terminal lying flush with a pin passing through both the metallized surface of the substrate which is in contact with the bottom of the housing and the thickness of the substrate, in order to come into electrical contact with at least one track or band on the other surface of the substrate.
Claim 5
Dependent Claim
57 words
Housing according to claim 1, characterized in that the substrate comprises several metal layers separated from each other in its thickness, the contact terminal of a pin coming into electrical contact with one of the external layers and the electrical connection between these layers being effected via metallized holes formed in these layers and in the substrate.
Claim 6
Dependent Claim
31 words
Housing according to claim 1, characterized in that the substrate is covered on its two surfaces by metal layers interconnected by lugs according to the interconnection method called "dual layer TAB".
Claim 7
Dependent Claim
22 words
Housing according to claim 1, characterized in that the conductor track or band is soldered onto the contact terminal of the pin.
